Good staff, good intent, decent entertainment. More seat space would always be of benefit

Qatar airways from Doha to guangzhau was excellent big bird Boeing 777 more room and smoothly flight, I Love it

They made us deliberate waste time by holding our passports and boarding passes making us miss the flight

I found it weird that the quality of the flight different from Australia to Doha than the Doha to Berlin leg. The quality of the toiletries pack (was in a box from Australia) and then a proper bag from Doha. The biggest variation was the inflight entertainment, which had a significantly shorter amount of content compared to the Doha flight. My QSuite seat was also broken and did not recline all the way flat. Wasn’t the best and I wouldn’t be happy if I’d paid cash for the flight.

Bad experience with the delay n long wait time for connecting flight after missing the connection flight from Doha.

All over with Qatar airlines my experience was really bad due to delays and then putting me on different airlines and after 8 hours of wait I had to listen to their is no plane to fly for another 24 hours. Wore experience ever.

I didn't understand why I got dropped off at departures on exiting the plane at Doha aiport. I had to find my own way to immigration/baggage reclaim which wasn't easy as staff in the departure section just tell you ti scan your boarding pass. This was very poor b qatar Airways. I spent 2 hours soyung this out and once I got to get my suitcase it was delayed. So instead of getting to the hotel at about midnight I got there at three in the morning. I wonder why I upgraded to business?

After going through security and waiting for the flight at the gate, there was no access to bathrooms and no place to charge a phone while waiting for the flight. But once I was on the plane, everything was very good.

Boarding process was terrible. Will not travel Qatar Airways if I had an alternative. The food was one of the worst, even for airline food.

Was unable to check in via app or website with supplied booking code (something to do with flight being operated by a partner airline, although the code didn’t work on the partner’s website either) Specified a vegetarian meal during booking, but that somehow wasn’t captured in airline’s system By the time flight crew got to my row, now vegetarian food was available. Had nothing to eat on flight from Philadelphia to Doha! Flight attendant was completely unconcerned and actively apathetic to the situation

Great service, great food, and comfortable business class seats... Friendly and professional flight attendants and ground crew, overall 5 star experience!

I was in business class, without the business class amenities. Large seat with lots of legroom, but no TV or bed. Food was okay, but I did enjoy the Turkish red wine.

This aircraft is not up to standard - old Airbus with terrible chairs and entertainment system for business class!

It was a nightmare. I booked business class ticket from Ediburgh to Beirut via Istanbul to attend a funeral. I had a wonderful experience flying to Istanbul from Edinburgh. Then I could not get a boarding pass issued to Beirut. It seems that although they booked me and I had a reservation number, I had no seat allocated and the flight was full. I was asked to go from one desk to another and made to wait for 2 hours. I missed my flight as I did not have a seat assigned and it was full. The only option was to put me on the next flight, 6 hours later, for a fee of over $400. They said that was the best they can do to 'help me' and to 'take it or leave it'. Well, I was not about to be bullied; I stood my ground. I booked and paid premium for the journey, which was confirmed. The eventually accepted to not charge me extra and i waited a total of over 8 hours in the airport with no compensation. On top of my grief with the risk of missing the funeral service, I had to put up with their indifference and condescending attitude. They spoke about me in Turkish thinking I would not understand (I hold a British passport) in front of me. When they eventually handed my passport and boarding pass back to me, I showed them I was born in Istanbul and that I understood everything and said a condescending 'thank you' back to them in Turkish. You should have seen their faces. I said that consumers have rights and it is a shame that Turkish Airlines does not have good customer service to at least acknowledge and apologize for errors committed by the airline. Blaming the me, the client, for such an error and placing unreasonable ultimatums, rudeness and dismissiveness to be rid of me, particularly when I was vulnerable and visibly grieving was really shocking... The airline taints the city of Istanbul and the people of Türkiye. Such a shame.

Boarding did not have a clue what is an EU disability card

Multiple errors by Turkish airlines and Istanbul Airport kept us from making flight. Stuck in Istanbul!

My mother got sick and dying and i have to change my flight and they charged me $2260 that is redisclose.

My flight had two legs. When checking in at the first leg the agent offering for a deal to upgrade the leg to first class for $199. He then claimed I would be able to upgrade the second leg once I got to the next airport. I declined and when I inquired about upgrading at the second airport, the cost was $1,300. I also had an issue at the airport lounge. I am allowed one guest in the lounge. My friend came in the lounge for less than 5 minutes and left when she couldn’t get a sleeping suite. I wanted to bring in another friend. The airport staff first started acting as though they didn’t understand English and then became upset when I asked for their names so I could file a complaint. As an elite member I knew they could do more but were not. One of the agents started over talking me and walked away mid conversation dismissing my request for assistance. A man claiming to be the manager said you were asking for her name. He also never tried to assist me or see what was going on. He claimed the interactions were recorded and management would see everything. I’m not sure how that would assist me days later. I am sure it didn’t help that I was a black American woman.

No wifi at all during the entire flight from Istanbul to Miami.

Our itinerary was broken apart by ChatDeal and let off our luggage from Turkey to Greece!! When contacted by this prior to our departure, I was informed it was my fault...I had to pay for checked bags, in middle of our trip! Turkish Airlines is not to blame for my distain of the ChatDeal interaction. COMPLETELY UNSAT!!

The seats are much too narrow and the arm rests are hard and awkwardly high, resulting in shoulder cramps. I am an average sized person ( definitely not overweight). The seats are a similar size to car seats with the added discomfort of incorporating hard plastic arm rests, that force average height individuals (I'm 5 ft 7 (f)) to hold their arms uncomfortably for several hours. The seats are much too close to the ones in front and behind making it extremely difficult to allow fellow passengers to get out, especially when the seat in front is declined. The leg room also necessitates knees banging into passengers backs for the entire flight. This used to be a quality airline who now offer mediocre service for premium cost, coupled with charging exorbitant prices for basic needs, like a seat, or luggage. Blatant and unabashed gouging of clients.

Staff was rude in business class. Luggage was damaged and nothing was done about it airlines.

Only problem we experienced was not anything to do with Lufthansa. When changing planes in Frankfurt we spent over an hour on passport control line. Lufthansa did a marvelous job on everything from keeping me informed via texts, to terrific cabin crew.

Another 35 min delay landing No apology no communication or acknowledgment about this

Try to humanize onboarding and take AI out. It's embarrassing and useless

Already stated....flights were fine. Late luggage a disappointment and failure my Lufthansa to get my bag delivered in a timely fashion.

I always try to book flights that don’t charge for baggage. Yet I was charged $75 for this flight.

We were helped whenever needed and had a pleasant flight.

Overall good experience. Polite crew. Good foodandentertainment. Seats are small and bit congested though.

I ended up buying (for $340) "extra space" seats because I my flying partner was given a STY boarding pass, leading me to conclude that she was on standby and that we had to buy seats on the flight. I later learned that the flight was not sold out and that we could have gotten on as usual. To be honest, I felt swindled.

Cardiff is a great airport but they pen you in at a gate way too small for passenger numbers. Called to the gate too soon and air conditioning was not in operation despite the heat. Cardiff should do better as a small relatively quiet regional airport.

This was one of the best travel experiences we've ever had with Ryanair. The flight boarded on time in Dublin, departed on time, and arrived on time in Split, even though the flight was full. The aircraft was clean, and all members of the cabin crew were both friendly and efficient. Even our fellow passengers were well behaved! So top marks to all concerned!

Good, everything went straight forward and on time, I am satisfied

Due to long security check and no last call announcements from Gate staff, my family and 12 other passengers missed the flight.

Perfect timing, perfect departure, lovely crew on the ground and in the air.

Good flight. Take off a little late but make up the time

Everything’s went straight forward, no issues, good service and friendly crew

Left on time and arrived on time both ways, thank you

Ryanair is the worst airline in Europe and easily one of the worst in the planet

The flight was 45 mins delayed but the crew provided water and necessities like tissues

Very bed boarding, there was overbooked and make a lot of problems and noises

On my way from Chicago to London, I was seated next to a quite heavy passenger. I could barely move. BA should have ensured that overweight customers are placed in comfortable seats and not to penalize also other passengers because BA is not willing to accommodate these passengers and their needs. No respect at all.

I truly don't think there was anything that could have been better. How is that for an endorsement?! I'm a firm fan of BA now, with two flights in the past 2 months. Keep up the great work! And thank you!

New airport for me. A little confusing.bunable to use kiosk for boarding pass. Agent checking us in was professional but not very friendly.

Taking off and landing were smooth. I didn't have anything to complain about.

The flight as far as timings go was excellent. Unfortunately we ended up sat with someone on a night flight who had been drinking alcohol before boarding and BA staff were happily serving him more alcohol. He was very drunk which made our flight uncomfortable and awkward. My partner had this person lying on him whilst asleep. Alcohol should be served minimally. If there had been an emergency this person would not have been in a fit state to act accordingly.

The sad case is that BA is often late. I missed my connection outbound and then was rebooked in another biz class seat some 10 hours later. I opted to change to economy (no compensation refunded of course) that was only 5 hours later. On the return journey, once again changing planes was very challenging. This time we landed only a little bit late, but deplaning took a long time so the connection was very much in doubt. Some serious running and sweat later, I managed to make the connection but my luggage did not. No messages about the missing luggage, so I had to wait until the entire bag return process was over before seeking out an agent. There was only one and well over 50 passengers waiting to speaking with her. She was quite pleasant, but it took 1 hour and 45 minutes from touchdown to leaving the airport.

First time flying with BA and I will do it again. Staff at airport and on board were very nice and helpful

BA charged me 70 euros for one bag on my return after having recognized my frequent flier status and charging me nothing for the same bag on the outbound. Their employees are not well trained and rules are inconsistently applied.

I couldn’t select my seat until I checked in at the airport. Extremely difficult to talk to a customer service representative. Also, the gate announcement doesn’t appear until less than an hour before boarding.
